On January 1, 2015, Skull Valley Motors leased a Lincoln Navigator to T. K. "Pusan Boots" Denny. The lease is a three-year lease requiring a payment of $695 at the end of each month for 36 months. The cash price of the Navigator was $46,000. Skull Valley Motors expects to be able to sell the Navigator for $30,652 when it is returned at the end of the three-year lease term.

1. What interest rate (compounded monthly) was used in the computation of the $695 monthly payment amount?

2. On December 31, 2017, Skull Valley Motors learned that the Navigator could be sold for only $25,000 at auction instead of the anticipated $30,652. With this actual residual value, what rate of return (compounded monthly) did Skull Valley earn on this three-year Navigator lease?

3. Assume that Skull Valley did not know about the decline in residual value until the Navigator was sold at auction for $25,000 in 2017. How much net profit, in total, was recognized during the three-year life of the lease, excluding the final sale of the Navigator at auction? How much gain or loss was recognized when the Navigator was sold for $25,000 at auction?

4. Refer to (2). If the rate of return on the lease is so low, why would Skull Valley Motors continue in the leasing business at all?
